诸广山岩体北部营盘圩地区铀成矿条件浅析
|
摘要
营盘圩地区位于诸广复式岩体北部,地处华夏板块武功—诸广断隆区,区域性北东向桂东—汝城断裂和遂川—热水断裂夹持部位。区内分布营盘圩、茶叶龙、九罗洞3个矿(化)点以及众多异常点。文章在前人勘查和研究工作的基础上分析了工作区铀成矿地质条件,认为该区具有丰富的铀源岩体和富铀地层;北东向小夏—黄坳断裂(桂东—汝城断裂带的一部分)为区内主干断裂,其旁侧次级断裂裂隙为主要控矿、容矿构造;多期次、多阶段蚀变叠加,造成了区内铀富集;晚期中基性脉岩发育,为成矿提供活化剂;地质调查、地面伽玛总量及土壤~(210)Po活度测量成果显示区内具有较好的浅深部铀矿化信息。综合分析认为,营盘圩地区具有较优越的成矿地质条件,值得进一步开展地质找矿工作。

Comprehensive analysis,the camp of Wei has superior ore-forming geological conditions and deserves further geological prospecting work carried out.
